namamahe tvam purusam puranam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O completely peaceful Lord, although material nature, fruitive activities and their consequent material names and forms are Your creation, You are unaffected by them. Therefore, Your transcendental name is different from material names, and Your form is different from material forms. You assume a form resembling a material body just to give us instructions like those of Bhagavad-gita, but actually You are the supreme original person. I therefore offer my respectful obeisances unto You.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Srila Yamunacarya has recited this verse in his Stotra-ratna (43):
bhavantam evanucaran nirantarah
“By serving You constantly, one is freed from all material desires and is completely pacified. When shall I engage as Your permanent eternal servant and always feel joyful to have such a fitting master?”
Manorathenasati dhavato bahih: one who acts on the mental platform must descend to material activities. Material contamination, however, is completely absent from the Supreme Personality of Godhead and His pure devotee. Therefore the Lord is addressed as prasanta, completely peaceful, free from the disturbances of material existence. The Supreme Lord has no material name or form; only the foolish think that the Lord’s name and form are material (avajananti mam mudha manusim tanum asritam). The identity of the Supreme Lord is that He is the original person. Nonetheless, those who have but a poor fund of knowledge think that the Lord is formless. The Lord is formless in the material sense, but He has His transcendental form (sac-cid-ananda-vigraha).
